Theriosuchus is an extinct genus of atoposaurid mesoeucrocodylian from Late Jurassic to Early Cretaceous of Europe (southern England), Southeast Asia (Thailand) and western North America (Wyoming), with fragmentary records from Middle Jurassic and Early Cretaceous sites in China, Morocco, and Scotland.[1]
Taxonomy
Three valid species are currently recognized: Theriosuchus pusillus from southern England,[2] T. grandinaris from Thailand,[3] and T. morrisonensis from the Morrison Formation of North America.[4] Theriosuchus was previously assigned to Atoposauridae, but a 2016 cladistic analysis recovered it as a neosuchian more closely related to members of the family Paralligatoridae than to atoposaurids.[1]
Two species previously assigned to this genus, Theriosuchus ibericus[5] and T. symplesiodon,[6] have been reassigned to the new genus Sabresuchus.[1] On the other hand, Theriosuchus guimarotae from Portugal[7] has been reassigned to Knoetschkesuchus.[8]
Paleobiology
Fossils belonging to the genus are abundant at several European sites, namely Dorset, southern England.
